This invention relates to the field of cable technology, specifically to a high-performance polyvinyl chloride (PVC) cable material and its preparation method. The cable material is based on PVC resin, combined with plasticizers and multifunctional flame-retardant composite fillers, with the filler content being 85-95 parts by weight per 100 parts by weight of resin. The multifunctional flame-retardant composite filler employs a multi-layered interface design: using magnesium hydroxide / calcium carbonate as the core, it first undergoes silane treatment to introduce epoxy sites, then constructs a phytic acid-tin-calcium-zinc chelate layer, and immobilizes double-grafted modified carboxymethyl-β-cyclodextrin, ultimately forming a tannic acid-metal ion polyphenol network layer. The preparation method includes pre-plasticization, segmented mixing with filler addition, and extrusion granulation. This invention effectively improves the filler-matrix interface compatibility, enhances flame retardancy, mechanical properties, and thermal stability, and solves the problem of insufficient durability in high-filler systems.

The application provides a high and low temperature resistant modified PBS material, a preparation method and an application. The modified PBS comprises the following raw materials in parts by weight: succinic acid: 100 parts; 1,4-butanediol: 110-130 parts; norbornene dimethylol succinic acid prepolymer: 15-30 parts; polyethylene glycol: 5-15 parts; a catalyst: 0.05-0.2 parts; an antioxidant: 0.1-0.5 parts; wherein the number average molecular weight of the norbornene dimethylol succinic acid prepolymer is 1000-2000 g / mol; and the number average molecular weight of the polyethylene glycol is 500-2000 g / mol. By introducing rigid norbornene bicyclic structure and flexible polyethylene glycol segments through chemical bonding, the high and low temperature performance of the PBS is synergistically improved, the modified PBS material can maintain stable mechanical properties in the range of-20 DEG C to 130 DEG C, meanwhile, the modified PBS material has excellent biodegradability, compatibility and processing performance, and the preparation process is simple and controllable, and is suitable for industrial large-scale production.

The application provides a low-temperature high-conductivity polyether electrolyte and a preparation method thereof. The polyether crosslinking network is formed by crosslinking polyethylene glycol monomethyl ether methacrylate and polyethylene glycol diacrylate, tri(pentafluorophenyl)borane and lithium salt are introduced to form a borane-lithium salt complex system, the molar ratio of lithium ions to borane is accurately controlled to be 1:0.02-0.20, and the acetonitrile complexing-vacuum desolventizing-in-situ polymerization curing process is used, so that the high-purity thin film electrolyte with the ion conductivity ≥1*10 ‑4 S / cm, residual acetonitrile ≤500 ppm and moisture ≤1000 ppm at low temperature is realized, technical problems that the low-temperature conduction capacity decreases when the crosslinking modulus of the traditional polyether electrolyte is improved, the processing window of the high-lithium salt system is narrow, and the interface stability of residual solvent and moisture is difficult to consider are effectively solved, and the low-temperature performance, processing stability and wide solid-state lithium battery application prospect are excellent.
